Industrial Automatic Control Systems and Controllers Annotation << Back The Methodic Bases of the Computing Experiment Implementation of the Information Security Study from Leakage Through TEMPEST Channels on the Informatizations Special Purpose Object in Condition of Effi ciency Checking Optimization of Information Protection from Leakage S.V. Skryl’, A.V. Shcherbakov, V.I. Spivak, M.V. Ponomarev The methodic of the computing experiment implementation using the mathematical models of the interception process features of the informative signals from electromagnetic and electric fi elds, process of checking to effi ciency of protection to information and information process in condition of interception threats and checking procedures realization is considered in the article. The purpose of the experiment is to determine the best checking to effi ciency of protection to information parameters’ values with designed mathematical models and to get scientifi cally reasonable requirements to directions of the improvement of checking procedures. The mathematical correctness of analytical models of proofs of the realization timeliness factors of the checking to effi ciency of protection to information procedures, realization timeliness of the information processes in condition of the interception threats of the electromagnetic and electric fi elds informative signal and checking procedures realization, as well as security information from leakage on channel TEMPEST on special-purpose informatization objects are given. The possibility of getting the scientifi cally reasonable requirements to directions of the checking procedures improvement based on mathematical simulation results with use of designed analytical model of the timeliness factors of the checking to efficiency of protection to information procedures realization is illustrated. Keywords: information leakage channel by means of TEMPEST; information protection effectiveness control from the leakage through the channels of TEMPEST; procedures realization timeliness of checking to effi ciency of protection to information; information processes realization timeliness in condition of interception threats of the informative signal of electromagnetic and electric fl ap and checking procedures realization, information protection from the leakage through the channels of TEMPEST.
